i can really relate to that...that my gf will keep saying that she and the guy were just friends, when its obvious that the guy is going after her.
ok since the i posted this thread, things have started to get better. I sat her down, i told her that the guys were really out to just get her. She knows that, but on her side, she just wants to maintain a friendship with the guy. So i told her to do an experiment, to tell the guy that they will only be friends and nothing more, coz she really loves her current bf, and to keep bringing me up, casually of coz. The result will be that either the guy will stop all activities with her and move on to another girl, or he'll step it up and confess soon. Either way, it'll show that the "guy friends" are not really "friends" afterall.
And guess what, they all stepped it up, did desperate and foolish things, and my gf start to see who are the real guy friends and who are the bastards trying to ruin us.
